INTERMEDIATE SCIENCE PHYSICAL SETTING KEY IDEAS AND PERFORMANCE INDICATORS

1. The Earth and celestial phenomena are described by relative motion and perspective

• explain daily, monthly, and seasonal changes on earth

2. Many of the phenomena that we observe on Earth involve interactions among the elements

• explain how the atmosphere, hydroshpere, and lithosphere interact, evolve, and change
• describe volcano and earthquake patterns, the rock cycle, and weather and climate changes

3. Matter is made up of particles

• observe and describe properties of materials such as density, conductivity and solubility
• distinguish between chemical and physical changes
• develop their own mental models tp explain common chemical reactions and changes in states of matter

4. Energy exists in many forms

• describe the sources and identify the transformations of energy observed in everyday life
• observe and describe heating and cooling events
• observe and describe energy changes as related to chemical reations
• observe and describe the properties of sound, light, magnetism, and electricity
• describe situations that support the principle of conservation of energy

**5. Energy and matter interact**

• describe different patterns of motion of objects
• observe, describe, and compare effects of forces on the motion of objects
